The purpose of this product is to develop the child's stereognostic sense, which creates a mental picture through touch. To help make the child more awake of the basic shapes found in the cultural environment. Indirectly, to prepare the child for later work in Mathematics, especially geometry, by identifying solid shapes and exploring the relationships between their plane and curved surfaces.
